A dark colored SVG Horizontal Bar chart

A Horizontal Bar chart with an offset X axis. The chart has a dark color scheme and uses the wave() effect. The dark background is achieved by setting the background color of the DIV tag (using CSS).

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.hbar.js"></script>
Put this where you want the chart to show up:
<div style="width: 750px; height: 500px; display: inline-block; background-color: #000" id="chart-container"></div>
This is the code that generates the chart:
